You should give more details about your configuration. If any client on the class B on NIC2 can contact your server, you must configure the NIC for the class B. The routing stack will take charge of excluding the class C on NIC1 from the class B on NIC2. It's very bad that the client that connects via the NIC2 has a subnet of class B and that the NIC2 is configured for class C only. If you configure: NIC1 192.168.1.1 255.255.255.0 NIC2 192.168.2.1 255.255.0.0 Client 192.168.127.23 255.255.0.0 it should work.
